This paper proposes a wearable hand rehabilitation device, DULEX, for persons with functional paralysis of upper-limbs after stoke. DULEX has three degrees of freedom for rehabilitation exercises for wrist and fingers except the thumb. The main function of DULEX is to extend the range of motions of finger and wrist being contracture. DULEX is designed by using a parallel mechanism, and its parameters such as length and location of links are determined by kinematic analysis. The motion trajectory of the designed DULEX is aligned to human hand to prevent a slip. To reduce total weight of DULEX, artificial air muscles are used for actuating each joint motion. In feedback control, each joint angle is indirectly estimated from the relations of the input air pressure and the output muscle length. Experimental results show that DULEX is feasible in hand rehabilitation for stroke survivals.

본 논문에서는 상지마비 환자의 재활훈련용 로봇의 인터페이스에 사용할 수 있는 데이터글로브를 제안한다. 데이터글로브는 7개의 유연한 각도 센서를 적용하여 손가락과 손목의 굽힘 각도를 측정할 수 있다. 개발된 데이터글로브의 성능은 3D 그래픽을 이용한 시각화로서 확인하였다. 실험결과로부터 개발한 데이터글로브는 손의 움직임을 측정하고, 인터페이스로 사용할 수 있음을 보인다.

Background and Objective: The Korean agricultural population is now rapidly aging. Older people in rural areas are weak due to work-related musculoskeletal disorders. The aim of this case is to report treatment of injuries to the nerves at the wrist and hand level by Korean medicine. Methods: The patient in this case was a 74-year-old male. He had injured nerves at the right wrist and hand level due to agriculture work. We treated him with acupuncture, herbal medicine, etc. Results: The patient showed the first sign of recovery of his wrist after 13 days treatment. After 37 days of treatment, his wrist movement was restored to a nearly normal range. He showed the first sign of recovery in a finger after 19 days of treatment and his grasping power increased from 0% to 60%. The cold sensation in his hand and arm also disappeared. Conclusions: We cannot generalize based only on this one case study. Nevertheless, this report suggests that Korean medicine may be an effective treatment for injury of nerves at the wrist and hand level.
